Why were federalist leaders not satisfied with having gotten only nine states to ratify constitution

Even though, the 9 states that ratified the Constitution were enough to take it into effect to the ratified states, New York and Virginia did not join in. These two are key states of the country and they held great power and influence. The Federalist leaders were not satisfied because: The country would be fragmented if New York and Virginia didn’t ratify the Constitution. I hope that helped :)
